      <H2>About</H2>
      <P>GEOS (Geometry Engine - Open Source) is a C++ port of the
         <A HREF='http://www.jump-project.org/project.php?PID=JTS&SID=OVER'>Java Topology Suite</A> (JTS).
         As such, it aims to contain the complete functionality of JTS
         in C++.  This includes all the OpenGIS "Simple Features for SQL"
         spatial predicate functions and spatial operators, as well as
         specific JTS topology functions such as <code>IsValid()</code>.
